Atherosclerosis and ischemic cardiomyopathy in a captive, adult red-tailed hawk (Buteo jamaicensis).

An adult, male, captive red-tailed hawk (Buteo jamaicensis) of at least 19 years of age presented in dorsal recumbency. The hawk was nonresponsive, and despite initial supportive care, died shortly after presentation. Gross postmortem revealed no abnormal findings. Histologic examination demonstrated atherosclerosis and ischemic cardiomyopathy. This is the first reported case of atherosclerosis in a red-tailed hawk.
